Hi folks - Here is the Friday Element Quiz: The Question: This element has been described as a "workhorse element". It is a low melting, low stiffness metal with moderate strength. In humans, a daily intake of 15 mg of this element is recommended. A deficiency of this element in the human body can cause deformed fingernails and delay the onset of puberty for several years. This element's low melting point results in room temperature recrystalization behavior measured in seconds. Its crystal structure is HCP. The element ranks 4th in annual production behind Fe, Al and Cu despite it not being very abundant in the Earth crust. What element am I? Bonus point question: What is this element's abundance in the Earth crust as measured in ppm? The Answer: The element is Zinc (Zn)! Zinc is more widely used than most folks realize. My resources show Zinc's crust abundance as 76 ppm. So the winner of this week's quiz is Bev Christian of RIM and Mike Laroe of Cirtronics was the closest on the Bonus question. It turns out that Doug is NOT in Florida this week so I can't send Bev his stapler. And I can't send him his son for lab duty as that would be a violation of International Trafficking laws. I'll tap into the Diet Mt. Dew tank and send up a gallon of soda instead. Everyone have a great weekend.
